Time saver! Fabulous!This scoop free self cleaning litter box from Boqii is a great product! I have 2 big 12 lb cats that use this litter box and the specified time for 2 cats under 15 lbs is 10 -15 days.No more cleaning out litter boxes every day, sometimes 2 times a day, instead, since I have 2 kittens about every 3 days after the downloaded app notifies me that the drawer is full, I pull out the drawer in the bottom lift out the used kitty bag, tie it up, then after placing a clean bag in the drawer I shut it, throw away used bag and reset the app... SO EASY! Much better than cleaning out 2 litter boxes every day and scrubbing to make sure the smell is gone! The only thing I would like to see an improvement on is I would like for it to be a little bit bigger to give my cats more room to move in it. But overall I love this product because it has made the litter box so much easier cause I don't have to scoop anymore and I don't have to smell any bad odors from a litter box and I save money on cat litter by using this system with the litter. If you have cats with a traditional litter box then I highly recommend to give this product a try because you will love it!Exceeded my expectationsA great product! I couldn't wait to use it when it first arrived in my hand. I followed the instructions for installation, and found that it was not difficult to install, a few simple steps I installed the large object,and to be honest, it's really too good for busy people like me, I can finally stop cleaning up my cat's poop every day and save time to finish my work or take care of my child. But if I do not clean up cat feces every day I am afraid that there is a very bad smell at home, I tested this product for a few days, it turns out that there is really not as bad smell as before, which I am satisfied. In addition, I can control this machine just through my phone every day, and I can see my cat's health data every time after she use the box, which gives me peace of mind. It will only work when the cat is using it, not when the cat is near it as well, the gravity sensor of this product is very practical! What I didn't expect was how easy it was to disassemble this machine when I wanted to clean it.
